ROLLING APPARATUS.

Application filed. March 29, 1926. Serial No. 98,108.

This invention relatesto apparatus for rolling the lining of arcuate brake shoes, preferably yieldingly by arranging a heavy springto urge the roller against the lining. In one very desirable arrangement, the roller is carried by a lever arm fulcrumcd at the center of the arc of the shoe. and the shoe is supported. at its ends and at an intermediate point. I prefer to arrange the parts so that they may be adjusted relatively to. the fulcrum of the lever arm, to permit rolling shoes curved on arcs of different radii,-

i. e. shoes of different sizes.

The above and other objects and features of. the invention will be apparent from the following description of one 'illuStrative embodiment shown in the accompanying drawing. in which:

Fig. l is a top plan view of the apparatus, with a brake shoe shown in position in dotted lines;

Fig. 2 is a section through the apparatus on the line 2-2 of Fig. 1; and

Fig. 3 is a detail section on the line 33 of Fig. 1. y

The illustrated apparatus is intended for rolling the lining of an arcuate brake shoe 12, which shoe is fully described in Patent No, 1,567,716, granted Bendix Brake Company Dec. 29, 1925, on an application filed by Adiel Y. Dodge. The apparatus may include. or be mounted on, any suitable bed or base 14-.

One end of the shoeis' supported by a pin 16, which may be inserted in any one of three holes 18, and which may be threaded or not as desired. The pin isformed with a collar '20, the top of which forms a shoulder supporting the lower one of the two arms 'l'orn'iinn' the fork at the end of the shoe.

The opposite end of the shoe engages an al'iutment 22 having a ledge 24.- on which the side of the end of the shoe rests. Abutment '22 is held by a pin 26 (threaded if desired) insertible into. any one ol three (or more) openings 28, and by a similar pin 30 insertible in any one of three (or more) openings y If the shoe is too long to rely on its own rigidity against springing, it may additionally be supported at an intermediate point by one or more pins 34, the oneshown being carried by abutment 22 and being arranged to engage the inner edge of the web.

The shoe may also be supported by one or and having the ends of more pins 36, engaging the bottom of the Web of the shoe, to prevent tipping. This pm may be inserted in any one of several openings 38.

The lining is rolled down by a roller 40, shown journalled in a U-shapedcarrier 42, 7 its spindle 44 pro 1ecting through guide slots 46 in a member 48 which, with a handle 50 of any desired length, forms a. level arm. fulcrumed on a pin 52 at the center of the arc of the brake shoe. Roller 40' is urged against the lining by a heavy coil spring 54: sleeved on a stem 56 carried by carrier 42.

Member 48 has several openings 58, for the fulcrum part 60 n'iounting the lever arm on pin 52, to permit lengthening the lever arm for shoes of different sizes. Openings 18. as, bodiment illustrated, permit rolling the linings of shoes for brakes 12, 14, and 16 inches in diameter.

Ki l) 32, 38, and 58, in the particular em- It is important to note that running the I roller off either end of the lining, and then to project away from the shoe at tangents.

By riveting againstflattcned spaces, and then breaking down the lining with the roller, this is effectively prevented.

\Vhile bne illustrative embodiment has been described in detail, it is not my. intention to limit the scope of the invention. to that particular embodiment, or otherwise than by the terms of the appended claims.

I claim: Y

1. Apparatus for rolling; the linings of arcuate brake shoes comprising, in combination. an abutment for one end of the shoe. a fixed pivot to support the other end of the shoe. a support adapted to engage an intermediate part of the Web on the inner side of the shoe. a roller adapted to engage the lining on the outside of the shoe, a lever arm carrying the roller and. fulcrumed at the center of the arc of the shoe, and a spring for urging the roller against the shoe.

2. Apparatus as defined by claim 1, in which the various parts may be adjusted relatively to the fulcrum of the lever ar m to permit rolling the linings of shoes having radii. of different lengths. I

Ap amtua for rolling the linings of arcuate rake shoes bomprising, in comhinw Hon, an abutment for one end of the shoe, :1 fixed pivot to support the other end of the she, a roiler adapted to engage the lining on the outside of the shoe, a lever arm carrying. the roller and fulcrumed at the center 0% the are of the shne, and a sprixw for urging the roller against the Shoe :mfi towardpaid center.

In teskimony whereof, I hav e hereuntosigned my name.
